IMPROVEMENT IN WAGON-AXLES.

Specification forming part of Letters Patent No. l0S.607. dated October 25, 11-70.

To all whom it may concern:

Be it known that I, WILLIAM A. LEwIs, of the city of J oliet, in Will county, and State of Illinois, have invented certain new and useful,

Improvements on aVagon-Axle; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, in which- Figure 1 is a longitudinal sectional view of the spindle and part of the axle; Fig. 2," aper- Fig. 3, a cross-se'c'-' spective View of the axle; tional view of the axle at the inner end of the spindle d, and Fig. 4 a cross-sectional view of the king-bolt and clip at the center of the axle.

The first improvement I claim to have made is in the use of a pipe or hollow tube, u, having the ends'swaged to at-aper to form the spindle (Z of itself, without the use of skeins or other external additions as bearings for the boxes to wear on, as shown in Fig. 1. I

' case-harden the spindle d,so as to make it hard,

The wroughtthat it may wear along time. iron collar 0 is shrunk on to form a shoulder for the hub to run against.

Another improvement I claim to have made is in the king-bolt clip, and the arrangement of the bolt at the center of the axle. The king- 'bolt i passes through the clip m, which is held in place by the bolts 0. The upper part of the Patent, is as follows:

1. The hollow-taperel case-hardened spindle (1, formed on the axle a, and being a prolongation of the hollow axle a, so as to dispense with a separate skein, asdeseribed and shown. 2. The combination of the clip m, bolts 0, king-bolt i, and axle a, constructed and arranged substantially as and for the purposes set forth.

'3. The combination of the collar a, hinge r, and axle a, constructed and arranged as and for the purposes set forth.
